Schematically showing of the parts utilized by the embodiment of the system 59 according to present disclosure has been shown in Fig. 5.As previously described, PC 40 can utilize cable 43, be connected to display device 28 via USB port 42.In alternative embodiment, wireless adapter can be inserted in USB port 42, thus PC 40 or other electronic equipments can be connected to display device 28 by wireless network.This can provide and user is wirelessly read from the output of automation controller 14 or wirelessly to the other benefit that automation controller 14 is configured.In arbitrary embodiment, display device 28 can comprise interface switch 60.In some embodiments, as shown in Figure 6, interface switch 60 can be incorporated in display device 28.In other embodiments, interface switch 60 can be positioned at display device 28 outside (such as, in automation controller 14).The operation of interface switch 60 is discussed below in detail.Return Fig. 5, interface switch 60 can be connected to automation controller 14 via cable 61 in communication, and this cable 61 is attached to the serial interface port on both automation controller 14 and display device 28.In this way, interface switch 60 can by giving tacit consent to Presentation Function (such as, when do not detect USB port connect or the traffic from this port time) and USB adapter functions (such as, when detect USB port connect and the traffic from this port time) between carry out switching and enable user access automation controller 14 from PC 40 or other electronic equipments.
As found out in figure 6, PC 40 can be connected to display device 28 via cable 43, and this cable 43 is attached to the USB port 42 in the front panel being embedded in display device 28.USB port 42 can also be connected to the interface switch 60 be included in display device 28.As previously described, when interface switch 60 detects with the physical couplings of USB port 42 and the traffic from USB port 42, interface switch 60 can make attached PC 40 can communicate with automation controller 14.In some embodiments, interface switch 60 realizes this point in the following manner: monitor the sensor that detection connects and monitor the data volume by USB port 42, then by forming the communication between the convenient PC 40 of communication path and automation controller 14, this communication path enables data flow through USB port 42, then outflow serial interface port 62 from PC 40 and arrives automation controller 14.The comparatively detailed view of the internal part of the embodiment of display device 28 is described referring to Fig. 7.
In the figure 7, two kinds of basic manipulation modes are shown.First mode performs display (such as text) function by activating Presentation Function circuit 64, and the second pattern performs USB adapter functions by activating USB adapter functions circuit 66.In some embodiments, when not detecting that USB port 42 connects or the traffic from USB port 42 do not detected, default mode is set to activate Presentation Function circuit 64.When such as PC 40 is connected to display device 28 via USB port 42 to electronic equipment, interface switch 60 can utilize and detect logic to detect connection.This detection logic can be provided by the firmware be embedded on following chip: this chip is arranged in display device 28 grade.If place detects that USB connects in USB port 42, then interface switch 60 can also detect the data traffic whether detected from USB port 42.To connect and from both data traffics of USB port 42 if interface switch 60 detects USB, then interface switch 60 can switch mode to activate USB adapter functions circuit 66.After completing this and switching, PC 40 can via display device 28, by sending through USB port 42 and communicating with automation controller 14 from the data that serial interface port 62 exports.
Once user completes the access from PC 40 pairs of automation controllers 14, PC 40 can disconnect with the USB port 42 of display device 28.When such an event occurs, interface switch 60 can sense this and disconnect (such as, physics cable removes or the traffic do not detected) and the pattern switching the capable Presentation Function 64 of receipt, thus makes it possible to check configuration from display device 28 and export.It should be noted that in this embodiment, owing to interface switch 60, only a kind of pattern can be accessed at every turn.But, as shown in Figure 8, in some embodiments, multiplexer 70 can be used to replace interface switch.Multiplexer 70 can make it possible to execution two kinds of functions (64 and 66), even if also like this when PC 40 is connected to display device 28 via USB port 42.Such as, when being connected with PC 40, the screen of display device still can display translation but may be placed in a reading mode, to avoid deadlock between Presentation Function circuit 64 and USB adapter functions circuit 66 or read/write conflict.In this way, substantially via PC 40, visit automation controller 14 by serial interface port 62 while, user still can check output on display device 28.
In addition, some embodiments can comprise as shown in by the process flow diagram in Fig. 9, for the method 80 of the operation of display device.Method 80 comprises: at block 82 place, receives input at interface switch place.As previously discussed, interface switch can be installed in the display device.Described input can come from display device self (such as, user presses the enter key on display device) or come from the electronic equipment such as PC being connected to display device via USB port.Thus, at decision block 84 place, display device then determines whether to detect that USB connects.If do not detect that USB connects, then the method can perform display (such as text) function, as shown in block 86.This operator scheme is the default mode for display device, this is because electronic equipment may usually only connect based on demand (such as, for reprogramming, download, upload).But if at execution USB adapter functions before display device, then this step may relate to and uses interface switch to switch to Presentation Function from USB adapter functions.In either case, method 80 can be back to block 82 to wait in the reception input of interface switch place after execution block 86.
But if detect that USB connects, then method 80 can determine whether the traffic to be detected further, as shown in decision block 88.If the traffic detected, then according to block 90, the method can perform USB adapter functions.It should be noted that the traffic can be defined as the request of the USB port between display device and attached electronic equipment and response or inflow and flow out the data of this USB port.If display device is at execution Presentation Function before both USB connection and the traffic being detected, then this step may need to be undertaken switching to perform USB adapter functions by interface switch.If the traffic do not detected, then the method can proceed to block 86 and perform Presentation Function.Therefore, in order to make interface switch switch to the pattern performing USB adapter functions, not only must detect that USB connects, and such as must there is communication between PC at display device and external electronic device.In some embodiments, detect and the physical connection of USB port or can the USB function of triggering block 90 by the traffic of USB port.
After method 80 performs USB adapter functions, it can be back to block 82 to wait in the reception input of interface switch place.As can be seen, in this way, method 80 can process USB cable from the scene that USB port physics disconnects or the traffic has stopped.In both cases, method 80 can determine no longer to detect that USB connects (block 84) or the traffic (block 88) no longer detected respectively, and can switch mode with the Presentation Function in execution block 86.Afterwards, method 80 can be back to block 82 with the other input of wait-receiving mode, thus can continue following circulation: switch back and forth to USB adapter functions from Presentation Function based on the input received at interface switch place.
Although illustrate and described only some feature of the present invention in this article, those skilled in the art will expect many modifications and variations.Therefore, it being understood that claims are intended to comprise all such modifications and variations dropped in true spirit of the present invention.
